Hall of Fame trainer Ignacio "Nacho" Beristain, the lifetime coach of former four division world champion Juan Manuel Marquez, admitted he was shocked by his boxer's one-punch knockout victory of Manny Pacquiao on Saturday night at the MGM Grand in Las Vegas.

so if nacho was surprised, that means they never really used the punch in camp that much, was it a lucky punch, a hail mary? not saying that it is but the trainer seems to point to that direction

No, because they clearly worked on it..there's that vid out where they show Marquez knocking down his partner with a short right that he stepped into..which prompted them to stop allowing the recording of his spars. This is just him showing how highly he thought of Pac. Obviously, with the name dinamita you've got some pop, but Nacho knows combinations is Marquez's bread and butter. It was just the culmination of everything. Pac took off like a sprinter into that right hand.

He means he wasn't expecting a one punch destruction of PAC- MAN , he knew the ko was possible but that was something else .. I hope Marquez retire , nothin else to prove . No better way to end a superb career .
